Abstract

The utility model relates to an electrical connector for electrically connecting a chip module to a printed circuit board. The electrical connector comprises an insulating body, a plurality of conducting terminals accommodated inside the insulating body, and a press plate defined with an unbuckling position and a buckling position corresponding to the insulating body. The press plate is provided with a first side edge and a second side edge, which are arranged oppositely; and a third side edge and a fourth side edge, which are arranged oppositely and connected with the first side edge and the second side edge. The four side edges enclose to form an opening. Elastic retention parts are arranged on the inner edges close to the opening of at least one pair of the side edges of the press plate. When the press plate is in the unbuckling position, the elastic retention parts clamp the chip module on the press plate, so that the chip module together with the press plate is turned downwards to the buckling position. Accordingly, the chip module can be pre-assembled on the press plate, so as to prevent the terminals from being damaged during the process of the disassembly of the chip module, thereby ensuring the stable electrical connection between the chip module and the printed circuit board.
